Abstract: In part 1 of this report, a procedure is described for the numerical solution of the time-dependent Navier-Stokes equations governing the forced convective flow in a crystal-growth crucible. By means of five digital simulations of the classical Czochralski crystal-pulling process, we show the excellent agreement of our calculations with the experimental data of Carruthers and Nassau [3], not only qualitatively but quantitatively, too. Moreover, for the Accelerated Crucible-Rotation Technique (ACRT) and its application to the Czochralski method (CACRT), the first numerical simulations are presented assuming the fluid model to be the same 1:1 glycerine-water mixture of moderate kinematic viscosities as in [3]. But our programme can also deal with low viscosities typical for semiconductors and liquid metals: This is demonstrated by our simulations of the classical Czochralski,the ACRT and the CACRT arrangements with the viscosity of liquid copper.
